HOLDER FOR LOOSE LEAF BINDERS Filed Oct. 1. 1927 Inventor Rebel-i J.Cope/an (J Patented Aug; 23, 1932 PATENT OFFICE ROBERr'LOOP AND, orTORONTO, ONTARIO, CANADA HOLDER}, F R LOOSE-LEAF BINDERS Application filed o cto ber 1, 1927. seriaino. 223,434.

The principal objects of the invention are to Overcome thedifiic-ultiesand' inconvenienoes m t with in the handling of loose leafbinders,.particu1ar1yin machine posting, and to facilitate the handlingof jbinders of the L shift type-in which the sections of the binderbackers manipnl'atedto alterthe relationship oi'the'prong on'ti edifferent sections. further important object-is to pr videif) a meansfor supporting the book so that the leaves will lie out-perfeotlyflat,no matter what portion of the book is" being used and which also" willafford means for an arm restin-making entries on the lower end'oi the i6Pages? T V v The principal feature of the invention consists inproviding a supporting member for the binder covers and leaves having arecessed h .4 portion adapted to receive the seotions of th hingedbinder back and further, to provide a-"po itive guidingelenient i said;recess to efieot'the desired positioning of' the binder backs: A Q Inthe drawin Figure. 1 isa; perspective '25 view ofa Iooseieaf bindershown supported by my improved device.

W f 1 Figure 3 is a pers ecti e view similar to Figure 2showing the shift binder baek moved in shifting the prongs. v r V vFigure 4 isan end elevation'alvie'w on a reduoed scale showing theposition of the binder back and support with the binder prongs separatedp Figure 5 is a perspective view of the holder showing one of th armsupports extended, Loose leaf binders, as at pres nt {3011; strnoted,are formed with metalbinderba'cks whiohare hinged centrally oftheiriwidth and are adapted' toswiiig open to separate theprongs so thatthe loose sh ets i be removed and rep1a ed',"bnt whenthe leaves are tobe tnrned I over the prongs have to be moved to overlapping position.These conditions require a considerable amount of manipulation andthebooks; very-heavy, consequently" much inconvenience is experi;-

enced. Further, when the hinge back is locked with the prongsoverlapping the pages will not lie flatr 7 Also in the type of binderknown as a fs'hift binder it is very difl'icult to hold the sheets atone side whilea shift is beingmade and the sheets frequently slip off.the prongs causing great inconvenience and loss oftim'e.

The present invention has been devised to overcome the above recitedobjections and to further 7 assist in" the handling of the book and itcomprises a holder 'on' which the book ei ,o

1 The holder as here shown is formed of a stiff board 1 which maybe ofmetal, fibre, Wood or heavy card havinga pair of ribs 2 6 arranged atthe ends and a pair of ribs3farranged adjacent to the centre. The ribs 3are preferably bevelled on their inner sides and a rib' 4, preferablybevelled on both sides is arranged centrally between the ribs The ribs 2and 3 are preferably formed with-longitudinal grooves 5 in their innerand outer sides-respectively and boards 6 having edge ribs 7 areslidably supported in the grooves; I i

The top su'rfacesof the boards 6 are preferably arranged flush'with'thetopsof the ribs and the spaces 8 beneath the sliding boardsform convenient pockets for holding spare sheets for the books usedthereon.

The holder thus described is placed upon a desk-and the,binder 8 isplaced thereon as shown in Figure 1. The hinged back is unlocked and thehinge sections rest in the parallel bevelled grooves formed between thecentre rib 4 and the adjacent ribs 3', as illustrated in Figures 1 and2. When the binder is thus placed. the points 9 of' the binder prongs 10are not separated so that the sheets I ll -may be removed but the'bindercovers 12 Q0 and the sheets 11 rest perfectly flat so that entries maybe made with the greatest ease. The sliding-boards 6' may be drawn out,

as shown; to form arm rests. It will be readily seen that as the pointsof the binder prongs are not separated to allow the sheets to come ofisuch sheets may be'turned as effecti'vely asif the binder back werelocked.

. If it be desired to remove sheets fromthe binder for machine positingor ther reasons When binders of the shift type are used.

the book is laid upon the holder and the back is unlocked and thesections then drop into the central grooves with the prongs overlapping,as shown in Figure 2 of the drawing,

the centre rib 4 acting .to break the hinge joint. The sheets may beturned as desired and when a shiftis desired it is merely neces-' saryto slip either half of thebinder, with the sheets arranged thereon,lengthwise of the grooves. vThis can be accomplished with the greatestfreedom and both hands can be used in making the shift without theoperator having to support or hold the hinder or sheets and there willbe no possibilityof the sheets slipping off the prongs andbecoming pied.I have shown a very simple form of construction of holder but it must beunderstood that the construction may be varied considerably so long. asthe holder is provided with a recess to allow the hinged back toopen andswing below the plane of the-underside of the covers. p

What I claim as my invention is: r Y '1. *A holder for loose leafbinders of the curved prong; type having a pair of hinged back sectionshinged to thecovers, comprising a flat board, transverse ribs arrangedat the ends of said board, and a pair of transverse ribs arrangedadjacent to the centre and forming a central transverse channel recessto receive and position the hinge sections of the binder back, the uppersurfaces ofall of said ribs being arranged in a common plane and formingrests adapted to engage and support thecovers of the binder in a commonplane.

2; A holder for loose leaf binders of the curved prong type having-apair of hinged back sections hinged to'the covers, comprising a flatboard, transverse ribs arranged at the ends ofsaid board, and a pair oftransverse ribs arranged adjacent to the centre and being bevelled ontheir opposing sides to form a centraltransverse channel recess ofangular cross section to receive and position the hinge sections ofthebinder back, all of said ribs having upper flat surfaces arranged in acommon plane to engage and support the covers of the binder in a commonplane.

' V 3. A holder for loose leaf binders of the curved: prong type havinga ,pair of hinged back sections hinged to the covers, comprisingsubstantially horizontal supports for the binder covers adapted tosupport the covers each in a substantially horizontal position tofacilitate entries, said supports being sepa- 35 rated'by a recess, thewalls of saidrecess be= binderback.

ing adapted to co-operatively engage and position the hinged sections ina predetermined angular relation relative to'the h0rizontally supportedcovers to effect the positioningof the opposing sets of prongs withtheir ends overlapping, said supports engaging the covers ontheiroutward sides in an extended manner to support theweight of the coversand sheets independent of the back members whereby the latter will befreely suspended within said recess for free manipulation therein.

4. A holder for loose leaf binders of the curved prong type having apair of hinged back sections hinged to the covers,comprising a rigid;member having a pair oflflat surfaces disposed in a commonplane ladapt-led to support the covers, in-theiropen posi-j tion and a, recessextendingcentrally thererfl' across to allow the/hinged back sectionsto, 3 be depressed below the'lefvel of the binder covI-j ers, the wallsof said recessbeing ada-pted to; engage and position said hinged backsections; to, support the prongs thereof in predetermined relation, saidsupports engaging the covers on their outward sides in anie xtendedmanner to support the weight ofitheocovers and sheets independentof thebackmembers whereby the latter will be freelysuspended within saidrecess for free manipulation therein] 1 f 5.
